Hi @GlockPL,
Thanks for the detailed issue description.
Unfortunately right now OpenFF's domain of applicability (that is, our infrastructure and force fields) only encompasses CHONPS+halogen elements. We may handle coordinated metals in the future (and in theory our force field specification is already ready for metals), but at the moment our published FFs and infrastructure will fail at multiple points if an input has metals.
You also might want to drop down to version 0.1.3 - release cannot complete the full fitting process and so we've yoinked it.
Ok, thank you for the info, I'll try downgrading.
Description I'm trying to find parameters for Zinc Ligand. But the problem is one of the step is to use rdkit MMFF94s filed to find charges, that field doesn't have Zn in it's atom types so it fails, is there work around this? Currently the problem seems circular. I need Zinc parameters in order to calculate Zinc parameters.
When I switch to PfizerFragmenter I come across another problem: "Failed to generate SMIRKS patterns that match both the parent and torsion fragments: (28, 29, 30, 31)"
Output:
Code for PfeizerFragmenter:
This is result of running just the fragementer:
